the us constitution of 1787, created the framework for government but did not guarantee rights for all groups.
the civil rights act of 1964, which outlawed discrimination based on race, color, religion, sex, or national origin

Explanation:

The Civil Rights Act of 1964 outlawed discrimination based on race, color, religion, sex, or national origin, directly expanding constitutional rights for marginalized groups (like racial minorities, women, etc.). The Declaration of Independence was about independence from Britain, the Seneca Falls Convention focused on women’s rights but was more of a social movement start, and the 1787 Constitution had flaws in rights (e.g., slavery, lack of women’s rights). So the Civil Rights Act of 1964 had the most significant impact on expanding rights for marginalized groups.

The Civil Rights Act of 1964, which outlawed discrimination based on race, color, religion, sex, or national origin
